Custom App distribution to more than 100 iPads

Hello Everyone,

Please if you can assist me with the query I have regarding on how I can distribute my custom app to more than 100 iPads.

I have a custom developed IOS App supplied by a vendor where I sign the app with my Apple Enterprise Certificate and Provisioning Profile and distribute to a group of iPads within my organization through a MDM.

With the plan I am on with Apple Enterprise Program - it only allows me to register a maximum of 100 iPads. However I now need to distribute this app to around 200 iPads.

Please assist with information on how I can increase my device count to more than 100.

Thanks Kavitesh
